Abstract (en)

A paper additive composition comprising an amide compound (a) obtained by reacting a polyamine and a carboxylic acid or a salt of the amide compound (a) is provided. The polyamine is shown by formula (1): R-(NH-R<1>)n-NH2 (wherein R is H2N-R<1> or R<2>, and each R<1> is independently an alkylene group having 1 to 4 carbon atoms, R<2> is an alkyl group or alkenyl group having 12 to 22 carbon atoms, and n is an integer of 1 to 3); the number of carbon atoms of the carboxylic acid is 10 to 24; the amide compound is obtained by reacting the carboxylic acid at a ratio of 0.5 to 4.3 moles per 1 mol of the polyamine; and the ratio of a tertiary amine value to a total amine value of the amide compound (a) is 0.60 to 0.99.
